Hom iav
Daim iav dav hlau
1.Dielectric txheej daim iav: Dielectric txheej iav yog ib txheej txheej dielectric txheej tso rau saum npoo ntawm cov khoom siv kho qhov muag, uas ua rau muaj kev cuam tshuam thiab ua kom muaj kev cuam tshuam nyob rau hauv qee qhov wavelength ntau yam. Cov txheej txheej dielectric muaj qhov cuam tshuam siab thiab tuaj yeem siv dav hauv qhov dav dav. Lawv tsis nqus lub teeb thiab kuj nyuaj, yog li lawv tsis yooj yim puas. Lawv tsim nyog rau cov tshuab kho qhov muag siv ntau lub wavelength lasers. Txawm li cas los xij, daim iav zoo li no muaj txheej txheej zaj duab xis tuab, rhiab rau lub kaum sab xis ntawm qhov xwm txheej, thiab muaj tus nqi siab.
2.Laser Rays Daim iav: Lub hauv paus khoom ntawm lub laser rays daim iav yog ultraviolet fused silica, thiab lub siab reflectivity zaj duab xis ntawm nws nto yog Nd: YAG dielectric zaj duab xis, uas yog deposited los ntawm electron beam evaporation thiab ion-pab deposition txheej txheem. Piv nrog rau cov khoom siv K9, UV fused silica muaj qhov sib xws zoo dua thiab qis dua coefficient ntawm thermal expansion, ua rau nws tshwj xeeb tshaj yog haum rau cov ntawv thov nyob rau hauv ultraviolet mus ze infrared wavelength range, siab zog lasers thiab imaging fields. Kev khiav hauj lwm wavelengths rau laser rays iav muaj xws li 266 nm, 355 nm, 532 nm, thiab 1064 nm. Lub kaum sab xis ntawm qhov xwm txheej tuaj yeem yog 0-45 ° lossis 45 °, thiab qhov cuam tshuam ntau dua 97%.
3.Ultrafast daim iav: Lub hauv paus khoom ntawm daim iav ultrafast yog ultraviolet fused silica, thiab lub siab reflectivity zaj duab xis ntawm nws nto yog ib pab pawg tsawg qeeb dispersion dielectric zaj duab xis, uas yog tsim los ntawm ion beam sputtering (IBS) txheej txheem. UV fused silica muaj qis coefficient ntawm thermal expansion thiab siab thermal shock stability, ua rau nws zoo tagnrho rau siab zog femtosecond pulsed lasers thiab daim ntaub ntawv siv. Kev khiav hauj lwm wavelength ntau rau cov iav ultrafast yog 460 nm-590 nm, 700 nm-930 nm, 970 nm-1150 nm, thiab 1400 nm-1700 nm. Qhov teeb meem beam yog 45 ° thiab qhov cuam tshuam tshaj 99.5%.
4.Supermirrors: Supermirrors yog fabricated los ntawm depositing alternating txheej ntawm siab thiab qis refractive index dielectric cov ntaub ntawv ntawm ib tug UV fused silica substrate. Los ntawm kev nce tus naj npawb ntawm cov khaubncaws sab nraud povtseg, qhov kev xav ntawm super-reflector tuaj yeem txhim kho, thiab qhov kev xav tau ntau dua 99.99% ntawm tus qauv wavelength. Qhov no ua rau nws haum rau cov tshuab kho qhov muag uas xav tau kev xav tau siab.
5.Metallic Mirrors: Cov iav hlau yog qhov zoo tagnrho rau deflecting broadband light sources, nrog siab reflectivity dhau ib tug dav spectral ntau. Cov yeeb yaj kiab hlau yog nquag oxidation, discoloration los yog tev tawm hauv qhov chaw muaj av noo. Yog li ntawd, qhov saum npoo ntawm daim iav hlau iav feem ntau yog coated nrog ib txheej ntawm silicon dioxide tiv thaiv zaj duab xis kom cais cov kev sib cuag ncaj qha ntawm cov yeeb yaj kiab hlau thiab huab cua thiab tiv thaiv oxidation los ntawm kev cuam tshuam nws qhov kev ua haujlwm kho qhov muag.
Lub kaum sab xis Prism Daim iav
Feem ntau, sab xis ntawm lub kaum sab xis yog coated nrog cov yeeb yaj kiab los tiv thaiv, thaum sab slant yog coated nrog cov yeeb yaj kiab uas muaj kev cuam tshuam. Lub kaum sab xis prisms muaj thaj tsam loj dua thiab cov kaum sab xis xws li 45 ° thiab 90 °. Piv rau cov iav tsis tu ncua, lub kaum sab xis prisms yooj yim rau nruab thiab muaj kev ruaj ntseg zoo dua thiab muaj zog tiv thaiv kev ntxhov siab. Lawv yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv kho qhov muag siv hauv ntau yam khoom siv thiab cov cuab yeej siv.
Off-axis Parabolic Daim iav
Daim iav off-axis parabolic yog daim iav saum npoo uas nws lub ntsej muag yog qhov txiav tawm ntawm niam txiv paraboloid. Los ntawm kev siv off-axis parabolic tsom iav, cov kab teeb sib luag lossis cov ntsiab lus sib dhos tuaj yeem raug tsom. Kev tsim tawm ntawm qhov chaw tso cai rau kev sib cais ntawm qhov chaw focal los ntawm txoj kev kho qhov muag. Siv off-axis parabolic tsom iav muaj ntau qhov zoo dua lo ntsiab muag. Lawv tsis qhia txog tus kheej kheej lossis chromatic aberration, uas txhais tau hais tias cov kab teeb pom kev tuaj yeem raug tsom ntau dua rau ntawm ib qho taw tes. Tsis tas li ntawd, cov kab hluav taws xob dhau los ntawm cov khoom siv hluav taws xob sab nraud muaj lub zog siab thiab kho qhov muag zoo txij li cov iav qhia tsis muaj theem ncua lossis kev poob qis. Qhov no ua rau off-axis parabolic tsom iav tshwj xeeb yog tsim rau qee yam kev siv, xws li femtosecond pulsed lasers. Rau cov lasers zoo li no, kev tsom xam thiab kev ua kom zoo ntawm cov nqaj yog qhov tseem ceeb, thiab cov tsom iav tsis zoo tuaj yeem muab siab dua precision thiab ruaj khov, ua kom pom tseeb ntawm lub teeb pom kev zoo thiab cov txiaj ntsig zoo.
Retroreflecting Hollow Roof Prism Daim iav
Lub hollow ru tsev prism muaj ob lub duab plaub prisms thiab ib daim duab plaub lub hauv paus phaj ua los ntawm cov khoom siv borofloat. Cov khoom siv borofloat muaj qhov sib txawv ntawm qhov chaw siab heev thiab cov khoom siv kho qhov muag zoo heev, nthuav tawm cov pob tshab zoo heev thiab tsis tshua muaj fluorescence siv nyob rau hauv tag nrho cov spectral ntau. Tsis tas li ntawd, lub bevels ntawm lub kaum sab xis prisms yog coated nrog ib tug silver txheej nrog ib tug hlau tiv thaiv txheej, uas muab siab reflectivity nyob rau hauv lub pom thiab ze-infrared ntau yam. Qhov nqes hav ntawm ob lub prisms yog muab tso rau ib leeg, thiab lub dihedral lub kaum sab xis yog teem rau 90 ± 10 arcsec. Lub hollow ru tsev prism reflector qhia lub teeb teeb meem ntawm lub hypotenuse ntawm lub prism los ntawm sab nraud. Tsis zoo li daim iav tiaj tus, lub teeb pom kev zoo nyob rau tib lub sijhawm rau qhov teeb meem teeb pom kev zoo, zam kev cuam tshuam ntawm lub teeb. Nws tso cai rau kev ua kom tiav ntau dua li manually kho ob daim iav.
